About the steam boilers:
Xenos WIGHT: Dick straight boilers have long been known to take the same Dobl boiler that stood on the car of his own name. It requires constant supervision of clever automation, while capricious, like a pregnant wife. And if a self-burning direct current boiler is placed on the boat under good pressure, the vibration will be very disturbing.

Xenos WIGHT: From the point of who sits next to you.
